Retrospective analysis enhances stone-free rates and reduces infectious complications in RIRS patients using ureteral access sheath.

Stone-free rates were significantly higher with the ureteral access sheath, showing a marked improvement.
Operative time decreased with sheath use, averaging 29.8 minutes compared to 46.5 minutes without it.
Infectious complications, such as fever and sepsis, were notably lower in patients using the ureteral access sheath.
Ureteral access sheath usage presented risks like mucosal injury and increased radiation exposure, necessitating careful patient evaluation.

Şanlı et al. (2025) studied this question.
